' 1 the following is a specification.

e nte -eat invention relates to a length i and the object is to provide an or manufacture of this chara ter h is flexible and ispermanently shaped a t isi'erse curve throughout its article being of any length. deit the same can be sold in a relah, from which portions or out as desired for individual 0, employed for any suitable for instance machine belting, or and binding any desired :t] all in 3. p "in. the accompanying drawing, Figure l is a. v w that is diagz'mnmatic in its character, i or eating a form of body blank that may be employed. 2 illustrates a section of the b ting: after the same has been given its i2 tial form. Fig. 3 is a detail view of a section of the completed article, and Fig. 4

, is a detail perspective view showing a rollof the same.

Similar reference numerals designate corresponding parts in all the figures.

rerrying out the invention, the body blank,

whi h may he of practically any 3 1, consists of flexible Woven having longitudinal and transverse distinguished from diagonally E This blank may be of any width, and it is preferably fiat, )ably preferred form, the central substantially inextensible, while one extensible. This Specification of Letters Patent.

From the foregeir s thought that the constrnetlen, 0 r id many advantages of the herein bee; invention will be apparen e thee, led in the art, without further 'iption, and it will be understood the various changes in the size, shape. proper n and'minor details of construction may a ing from the spirit or sacrificing any of the advantages oi the invention.

Having, Hi fully described my invention, what- 1 clan-n. new, and desire to secure 5; Letters Patent, is z'- As an a ticle of manufacture, a length oi belting ipiising a strip of W his material LVlIlQ' its long! it nal portions W the central p being saturated stance and having curvature 2. As an article oi niannfaetn of belting of woven flexible material having marginal portions that are woven more loosely than the central portions and having a permanent transverse curvature 3. As an article of manufacture, a length of belting of Woven flexible material having central longitudinal threads that are subblank,

resorted to without depart-' threads,said belting having a permanent transverse curvature.

4. As an article of manufacture, a length of belting; of woven material having central longitudinal threads that are substantially inextcnsible, and marginal threads that are more extensible than said central threads, the marginal portions of said belting being more loosely woven than the central portion, and said belting having a permanent transverse curvature.

5. As an article of manufacture, a length of belting formed of flexible woven material having longitudinal and transverse threads, said belting having a stiffening substance incorporated therein and having a permanent transverse, curvature throughout its length,

1 and a flexible substantially inextensible 1,1ss,see

holding elemeii secured longitudinally to the central por on of the belting.

6. As all artucle of manufacture, a length of belting of woven material having central longitudinal threads that are substantially inextensible, and marginal threads that are more extensible than said central threads, the marginal portionsof said belting being mo e loosely woven than the central portion, an said belting having a permanent transverse curvature, and a flexible substantially inextensible holding element secured longitudinally to the central portion of the body In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
